I've seen some objects with pretty_inspect get stuck in an infinite loop (or close to it), so they take literally hours to print. This function uses Timeout to prevent this. either the class prints quickly, or we kill it and try something else.

If the something else doesn't work, we just give up...

This does nothing in a normal report because reports are built as you go. If nothing has been reported though, this will create a report indicating that nothing happened.
